ShelTherm: A Simple Shelter Thermal Design Assistant

This is a tool and a physics-based model (ShelTherm) of the heat transfer and air flows through simple structures. A state of the art heat transfer (balance) method is encapsulated within the tool designed to be used by humanitarian staff. The only input is a very simple description of the shelter, and the output being the time series of internal and external temperatures over an example summer and winter day. It is important to note that, unlike other reduced models, the method is capable of dealing with high ventilation/inflation rates, thin materials (such as tarpaulin) and high U-values.
